Rated 3 out of 5 by from As a student i require the use of my laptop a lot & when the original charger that came with the laptop broke i sought this product as an alternative. Initially i was very impressed with the quality of the charger & the amount of accessories that come with it; however, after about a week of purchasing this product the tip that i needed to use broke. in my opinion, the tips seem very fragile & susceptible to breakages which is disappointing as nobody really expects a product like this to be breaking in just a matter of days after purchase. The rest of the product is of a quality standard but i do feel that maybe the tips could be reinforced to make them less fragile.

Rated 2 out of 5 by from Rubbish This item is overpriced for the amount of time it lasts. I bought it in an emergency for my laptop as it's previous charger broke. It has worked for a year and a bit, however today it made a popping sound and is no longer working, at no fault of my own. Therefore, it is not worth the large price that it is, because it has a short life.

Rated 4 out of 5 by from Very reliable charger. Doesn't smoke or create hazards. I like how it has volt key to choose its voltage, and how it has different laptop adapters and a USB power port to charge phones etc. It gets really hot but it's a good charger.

Rated 2 out of 5 by from Tips are dodgy Like a previous reviewer I have to agree that this product is let down by the quality of the bits that you actually plug into the laptop, as the one for my laptop has now stopped working after about 6 months of use.

I purchased this product years ago and it is still working fine. Unfortunately I have lost the tips which came with it. Can I buy a replacement set of tips, if so which ones do you recommend? Thank you.

Spare tips are listed at the following link, but like this supply, they have been discontinued and a such stock is very limited.

Please advise which laptop adaptor laptop adaptor outputs lowest ripple and noise on the HDMI audio output off a Lenovo Thinkpad. Present "replacement adaptor" results in noise and hum on the HDMI audio output. (Audio good on battery only)
